Cosmic noise
From Wikipedia, the free encyclopedia
Cosmic noise and galactic radio noise are random noise that originates outside the Earth's atmosphere. It can be detected and heard on radio receivers.
[edit] Explanation
Cosmic noise characteristics are similar to those of thermal noise. Cosmic noise is experienced at frequencies above about 15 MHz when highly directional antennas are pointed toward the sun or to certain other regions of the sky such as the center of the Milky Way Galaxy.
